We stayed at Bass Lake near Yosemite, nice CG, would stay again.
In Sequoia/Kings Canyon, we stayed at the Sunset CG in Kings Canyon NP--we loved it. We had to come in that way because of length restrictions on Sequoia's south entrance.
We also stayed at the Anaheim RV Park--right next to Disneyland and not far from the Queen Mary(if you like ghost stories--this ship is for you).
Valencia Travel Village is another big resort in Castaic---convenient if you want to see the sights of Hollywood or Malibu beach-nice drive through Malibu Canyon Rd.
Leaving Yosemite, we went over Tioga Pass on 120 to 395. Great scenery in Northern California and awesome little towns like Bishop and Lone Pine. We can't wait to return someday.
